Subfamily Chloridoideae (Poaceae) in the New World includes 72 genera (61 native, 11 introduced), 678 species (607 native), and, including intraspecific taxa, 817 total taxa. The five largest genera are Muhlenbergia (147 species), Eragrostis (111), Sporobolus (76), Bouteloua (57), and Chloris (35). Three tribes are recognized in this study: Cynodonteae, Eragrostideae, and Zoysieae, with ten, three, and two subtribes, respectively. Cynodonteae, the largest tribe, comprise 58 genera and 451… Expand

A molecular phylogeny and new subgeneric classification of Sporobolus (Poaceae: Chloridoideae: Sporobolinae)
TLDR
The phylogenetic analysis provides weak to moderate support for a paraphyletic Sporobolus that includes Calamovilfa, Crypsis, Spartina, and Thellungia, and the molecular results support the recognition of 11 sections and 11 subsections. Expand
A worldwide phylogenetic classification of the Poaceae (Gramineae) II: An update and a comparison of two 2015 classifications
TLDR
A new worldwide phylogenetic classification of 11 506 grass species in 768 genera, 12 subfamilies, seven supert tribes, 52 tribes, five supersubtribes, and 90 subtribes is presented and a radial tree illustrating the hierarchical relationships among the subtribes, tribes, and subfam families is included. Expand
Species delimitation in the Sporobolus aeneus complex (Zoysieae, Chloridoideae, Poaceae) using the phylogenetic species concept.
TLDR
It is concluded that leaf blade pilosity, widely used as a diagnostic character in the Sporobolus aeneus complex, is affected by external conditions like fire or blade age and is taxonomically unreliable. Expand
Phylogenetics of Muhlenbergiinae (Poaceae: Chloridoideae, Cynodonteae) based on ITS and trnL-F DNA sequences
TLDR
A phylogenetic study of Muhlenbergiinae based on parsimony analysis of DNA sequences of the nuclear ribosomal internal transcribed spacer region and chloroplast suggests two subtypes of C4 photosynthesis, NADME and PCK, are thought to occur in Mhlenbergia. Expand
Centropodieae and Ellisochloa, a new tribe and genus in Chloridoideae (Poaceae)
TLDR
A phylogenetic analysis of 127 species using seven plastid regions to infer the evolutionary relationships of Centropodia, M. papposa, and M. rangei shows they are sister to the remaining tribes in Chloridoideae and provides the carbon isotope ratios for four species indicating that Merxmuellera pappos and M- rangei are photosynthetically C3, and CentropODia glauca and C. mossamdensis are C4. Expand
A phylogeny and classification of the Muhlenbergiinae (Poaceae: Chloridoideae: Cynodonteae) based on plastid and nuclear DNA sequences.
TLDR
The phylograms suggest that Muhlenbergia originated in North America because the sister (Sohnsia filifolia and Scleropogoninae) is composed of predominantly North American species. Expand
A molecular phylogeny and classification of Leptochloa (Poaceae: Chloridoideae: Chlorideae) sensu lato and related genera.
TLDR
The molecular results support the dissolution of Leptochloa s.l. is polyphyletic and strong support was found for five lineages. Expand
A tale of North and South America: time and mode of dispersal of the amphitropical genus Munroa (Poaceae, Chloridoideae)
Plant disjunctions have provided some of the most intriguing distribution patterns historically addressed by biogeographers. We evaluated the three hypotheses that have been postulated to explainExpand
Agrostopoa (Poaceae, Pooideae, Poeae, Poinae), a New Genus with Three Species from Colombia
TLDR
Agrostopoa is placed in subfamily Pooideae because it has non-Kranz anatomy and lanceolate membranous lodicules, and in tribe Poeae where it differs from Agrostis L. by having carinate lemmas with a terminal awn or mucro, well-developed paleas, and peculiar synflorescences with recurved branches and fragile pedicels. Expand
Diversity of inflorescences in the Boutelouinae subtribe (Poaceae: Chloridoideae: Cynodonteae)
TLDR
The systematic and taxonomic value of the inflorescence in the Boutelouinae subtribe is discussed and characters and processes that may help to understand the group systematics are identified. Expand

Schaffnerella rediscovered! (Gramineae, Chloridoideae)
TLDR
Much additional field work is required to determine the geographic range and frequency of the species, and life history and population-level studies are needed. Expand
Studies on the origin, evolution, and distribution of the Gramineae. III. The tribes of the subfamily Eragrostoideae
TLDR
Geographical and taxonomic evidence indicates that the Eragrostoideae may have originated in tropical or subtropical Africa at least as early as the Oligocene and suggests that the subfamily is a very old one. Expand
Phylogenetics of Chloridoideae (Gramineae): a Preliminary Study Based on Nuclear Ribosomal Internal Transcribed Spacer and Chloroplast trnL–F Sequences
TLDR
The phylogeny of Chloridoideae (Gramineae) was inferred from parsimony analyses of DNA sequences from two genomes, and suggested significant homoplasy in morphological traits, including inflorescence type, number of florets per spikelet, and number of lemma nerves. Expand
On the Classification of the Chloridoideae (Poaceae)
TLDR
A series of phenetic and cladistic analyses has been conducted on generic descriptions of Chloridoideae and a new classification model for the subfamily is proposed, indicating five quite different high level groups. Expand
Distribution of sub-families of Gramineae in the Old World.
TLDR
Simple species counts are employed so that each sub-family may be mapped independently of the others, in view of the correlation between taxonomy at this level and differences in metabolism and photosynthetic pathway. Expand
Major Disjunctions in the Geographic Ranges of Seed Plants

  • The Quarterly Review of Biology
  • 1972
TLDR
In attempting to review and classify the major intercontinental disjunctions in the geographic ranges of seed plants, six guiding principles are followed where possible and possible explanations for the major discontinuities are discussed. Expand
Photosynthetic pathways and the geographical distribution of grasses in South West Africa/Namibia.
TLDR
Within the aspartate forming group the results show that it is specifically the NAD-me type of species which dominate in areas of very low precipitation, notably in the Namib and pre-Namib areas where rainfall is less than 200 mm/yr. Expand

TLDR
The phylogeny of Boute/oua and relatives (Gramineae: Chloridoideae) employing cladistic parsimony analysis of nuclear ribosomal internal transcribed spacer region was estimated using PAUP and suggested homoplasy in morphological, anatomical, and breeding system traits. Expand
